Hazardous Area
Hazardous Area
(OP)
BS EN 60079-14:1997 requires that no solid obstacle which is not part of the electrical apparatus shall come within a specified distance to a flameproof flange (e.g. 30mm for IIB Gas Group).
Would anyone know if there is any flexibility to this requirement, e.g a small bore pipe (10mm O/S diameter) 10mm from a EExd motor terminal box which itself is 150mm square.
Thanks,
Alan

In my copy of the BS EN there are no exceptions stated.
I would be interested to know if there are exceptions in the IEC version & the soon to be published BS EN?
